Hot Microsoft SharePoint Applications 70-486 Dumps Exam Questions And Answers (Q1-Q15)

QUESTION 1
You are developing an ASP.NET MVC application to be used on the Internet. The environment does not use Active Directory.
Users must be able to log on to the application to maintain their personal preferences.
You need to use the least amount of development effort to enable users to log on.
What should you do?
A. Enable Digest authentication.
B. Enable Windows authentication.
C. Enable Forms authentication.
D. Generate server SSL certificates and install them in IIS.
Correct Answer: C

Explanation:
Many Web applications require a way to restrict access to some resources (such as specific pages) so that those resources are accessible only to authenticated users. The default Web application project template for ASP.NET MVC provides a controller, data models, and views that you can use to add ASP.NET forms authentication to your application. The built-in functionality lets users register, log on and off, and change their password. For many applications, this functionality provides a sufficient level of user authentication.
Incorrect:
Not B: Windows authentication would require an Active Directory. Windows authentication method works only if the following two conditions exist:
/ You set up your network to use the Kerberos authentication protocol that requires Active Directory.
/ You set up the computers and accounts on your network as trusted for delegation.

QUESTION 2
You are designing an enterprise-level Windows Communication Foundation (WCF) application. User accounts will migrate from the existing system. The new system must be able to scale to accommodate the increasing load.
The new servers are experiencing significant stress under load of large-scale role changes.
You need to ensure that the application can handle the stress.
Which authorizations should you redesign? (Each correct answer presents a complete solution. Choose all that apply.)
A. Role-based approach
B. Identity-based approach
C. Resource-based trusted subsystem model
D. Resource-based impersonation/delegation model
Correct Answer: AC

QUESTION 3
You are developing an ASP.NET MVC application that will run in a shared environment.
The application requests the user’s password, and then uses the password to sign data.
You need to minimize the potential for the password to be discovered by other processes that run in the shared environment. What should you do?
A. Add the SecuritySafeCriticalAttribute attribute to the methods which process the password.
B. Store the password in a SecureString instance.
C. Encrypt the password on the web page, and decrypt the password in the MVC application.
D. Run the code that processes the password in its own AppDomain.
Correct Answer: D

Explanation:
Application domains provide a unit of isolation for the common language runtime. They are created and run inside a process. Application domains are usually created by a runtime host, which is an application responsible for loading the runtime into a process and executing user code within an application domain. The runtime host creates a process and a default application domain, and runs managed code inside it. Runtime hosts include ASP.NET, Microsoft Internet Explorer, and the Windows shell. For most applications, you do not need to create your own application domain; the runtime host creates any necessary application domains for you. However, you can create and configure additional application domains if your application needs to isolate code or to use and unload DLLs.

QUESTION 4
You are developing an ASP.NET MVC application that uses forms authentication. The user database contains a user named LibraryAdmin.
You have the following requirements:
70-486 dumps
You need to implement the controller to meet the requirements.

QUESTION 5
You are developing an ASP.NET MVC application. Devices that use many different browsers will use the application.
You have the following requirements:
70-486 dumps
You need to configure the application. 70-486 dumps
Which two actions should you perform? Each correct answer presents part of the solution.
A. Use JavaScript to evaluate the window.innerWidth and window.innerHeigh properties.
B. Set the value of the width property for the viewport meta tag to device-width.
C. Use CSS to target the HTML element on each page. Set the values of the width and height properties to 100%.
D. Use CSS media queries to target screen size, device orientation, and other browser capabilities.
Correct Answer: BD

Explanation:
B: If you want the viewport width to match the device’s physical pixels, you can specify the following:
<meta name=”viewport” content=”width=device-width”>
For this to work correctly, you must not explicitly force elements to exceed that width (e.g., using a width attribute or CSS property), otherwise the browser will be forced to use a larger viewport regardless.
D: Media queries in CSS3 extend the CSS2 media types idea: Instead of looking for a type of device, they look at the capability of the device. Media queries can be used to check many things, such as:
width and height of the viewport
width and height of the device
orientation (is the tablet/phone in landscape or portrait mode?) resolution
Using media queries are a popular technique for delivering a tailored style sheet to tablets, iPhone, and Androids.

QUESTION 6
You are developing an ASP.NET application that allows users to download Microsoft Azure log files. You need to improve the performance of the application.
What should you do?
A. Minify the content files.
B. Enable compression in IIS.
C. Bundle the content files into a single .tar file.
D. Host the image, JavaScript, and CSS files on a different server.
Correct Answer: C

Explanation:
Bundling is a new feature in ASP.NET 4.5 that makes it easy to combine or bundle multiple files into a single file. You can create CSS, JavaScript and other bundles. Fewer files means fewer HTTP requests and that can improve first page load performance.

QUESTION 7

Explanation:
A: We retrieve the GET and POST methods through
this.HttpContext.Request.RequestType.
B: This is the default MVC implementation of having separate methods for GET and POST via function overloading.
Incorrect:
Not D: We retrieve the GET and POST methods through this.HttpContext.Request.RequestType, not through this.HttpContext.Request[“ActionName”].

QUESTION 8

70-486 dumps
You need to correct the performance issues.
Which two changes should you make to the code? Each correct answer presents part of the solution.
A. Replace the code at line 07 with the following code segment:[OutputCache(Duration =30, VaryByParam = “none”, Location = OutputCacheLocation.Client, NoStore = true)]
B. Replace the code at line 12 with the following code segment:[OutputCache(Duration = 30, VaryByParam = “none”, Location = OutputCacheLocation.Server, NoStore = true)]
C. Replace the code at line 07 with the following code segment:[OutputCache(Duration = 3600, VaryByParam = “none”, Location = OutputCacheLocation.Server, NoStore = false)]
D. Replace the code at line 12 with the following code segment:[OutputCache(Duration = 3600, VaryByParam = “none”, Location = OutputCacheLocation.Client, NoStore = true)]
Correct Answer: AB

Explanation:
B: They report delays in seeing the latest game results. This is the output of the GetResults() function. We decrease the Duration in the cache for this function from 3600 to 30. This is one line 12.
A: They report seeing other user’s name when they sign in to the application. This is the output of the GetUserInfo() function. We should change the OutputCacheLocation of the caching of this function from Server to Client. This is on line 7.
Note: The OutputCacheLocation.Client option indicates that the content should be cached at the requesting client. Any requests for the same resource made from the same client within the expiry period, will be served out the client’s cache, without a network request being made to the server. The OutputCacheLocation.Server option indicates that the content will be cached at the origin server. This content will be served for subsequent requests made by the initial client and any other client requesting the same resource within the expiry period.

QUESTION 11
You are developing an ASP.NET MVC application.
The application must allow users to enter HTML in a feedback text box only.
You need to disable request validation.
What should you do?
A. Use the HttpRequest.Form property to read the unvalidated form value.
B. Apply and set the Validatelnput attribute on the controller action to FALSE.
C. Use the HttpRequest.Unvalidated property to read the unvalidated form value.
D. Apply and set the CausesValidation attribute on the controller action to FALSE.
Correct Answer: C

Explanation:
The HttpRequest.Unvalidated Property provides access to HTTP request values without triggering request validation.

QUESTION 12
You are designing a distributed application that runs on the Windows Azure platform.
The application must store a small amount of insecure global information that does not change frequently.
You need to configure the application to meet the requirements.
Which server-side state management option should you use? (Each correct answer presents a complete solution. Choose all that apply.)
A. Windows Azure application state
B. SQL Azure
C. Profile properties of the Windows Azure application
D. Windows Azure session state
Correct Answer: B

Explanation:
SQL Database provides a relational database management system for Windows Azure and is based on SQL Server technology. With a SQL Database instance, you can easily provision and deploy relational database solutions to the cloud, and take advantage of a distributed data center that provides enterprise-class availability, scalability, and security with the benefits of built-in data protection and self-healing.
Incorrect:
Not A: Application State does not exist in Azure. Not C: Profile properties stores personal, not global, information. Not D: Session state is not global. Session states handles user information such as cookies, hidden fields, and query strings are some client-side options to tracking user state
